These data can be shown on the display of the trip units, transmitted to the PROFIBUS-DP via the COM15 module or to the MODBUS via
the COM16 module and transferred to the outputs of external
c
modules. Based on these data, conclusions can be drawn about
the condition of the power system.

1)
The given measured value tolerances are valid for one year based on an average operating temperature of 25 °C. After this period, deviations may occur.
The given tolerances for measured values for which the measured voltage is consumed when being determined are only valid if the voltage measurement
is carried out with an accuracy of 0.5 %.
2)
ANSI definition:
Ratio of the largest difference between the phases and the average of all 3 phases.
